2 Claims.

I This invention relates to door looks or latches, andmore particularly to a lockfor the front door of a building, although it will be understood that it may be employed in any location in which is desired, a look having the novel characteristics embodied in the present structure.

The invention relates to a so-called tubular lock, and'embodies improvements over the lock shown in my Patent No. 2,268,973, of January 6, 1942. The structure shown herein is also similar in some respects tov that shown in my previous Patent No. 2,272,101, granted February 3, 1942. a

In' the embodiment shown the mechanism is provided with a latch bolt and also with -,a boltcontrolling or dogging plunger to dog the bolt when the door is closed against retraction by a tool inserted between the edge of the door and the door jamb. It is also provided; with means to dog the outside knob against rotation, which means is constituted by a plunger accessible from the face of the door and guided inthewallsof the case so that it may be pushed inwardly to dog the rollback of the outside knob. I

In my previous patent referred to,'No. 2,268,973,"

a walking beam structure is mounted in and can ried by the inner rose member of the lock to operate this knob-dogging plunger. In some instances it is necessary that this plungerhave a longer stroke than was permitted by the depth of the standard rose. In other words, as the walking beam was supported by and house-:lwithin the rose or between the outer surface of the rose and the door, the throw of the walking beam lever was limited by the depth of the rose, andin some instances the standard rose employed with other locks was not sufliciently deep to provide enough room to give the walking beam lever' the throw required to effect a sufficient movement of the dogging plunger. In that event it became necessary to provide a special rose, ora rose of greater depth than was standard for the walking beam structure shown in that patent.

One object of the present invention is to overcome the disadvantages above referred to, andito provide a lock having a dogging plunger go trolled by a walking beam mounted upon thedutside of the door but so arranged that the standard rose may be employed, and at thesame timeithe walking beam will be provided with the necessary movement or throw. j U

A still further object of the invention fis the provision of a lock structure similar to that shown in my Patent No. 2,268,973, wherein, the walking beam structure is mounted upon andcarriedgby a plate secured to the door, instead of being mounted upon the rose, whereby the supporting plate may berecessed or cut away to give the wallnngbeaman additional throw while the rose is abutted against the supporting plate so that the walking beam structure will behoused between the plate and the rose.

{A still further' object ofthe invention is the provision of a door-lock having a. device for dogging one oftheknobs against rotation, the operation ofiwhi device is effected by a walking beam mounted ,within the inside rose member, the construction being so arranged that a rose of standard depthmay be employed and at the same time the walking beam maybe provided with the necessarymovementor ,throw.

, ,Astillfurtherobject of the invention is the provision of; a dogging mechanism of the type previously described, in connection with a mortise look as distinguished froma tubular lock, shown 11117116; prior patents referred to- To these and-.otherendsthe invention consists in the novel features and combinations of parts to be, hereinafter described and claimed.

1 Fig: .1;0:.:is:a perspective view of the walking beam; and

Fig. 11 is al perspective view of the bracket which secures thewalking beam structure to the supporting plate. r To illustrate a preferred embodiment of my invention,, I, have shown a portion of a door at 10; on? which:is mounted a lock comprising a tubulancasing H having reciprocably mounted therein a bolt, lznormally urged outwardly by the :bol t -spring;,l3, which acts against the bolt head and against a post l4 provided on the walls of the casing. The lock may also be provided with a bolt-controlling plunger l5 which serves, as shown in my Patent No. 2,272,101, above referred to, and as is Well known in the art, to prevent the retraction of the bolt by a tool inserted between the edge of the door and the door jamb.

Rotatablyv mounted in. the walls of, the. casing are inner and outer hubs. l6 and l-T carrying; rollbacks I8 and I9, respectively, which serve to retract the bolt in the usual way. These rollbacks. are operated by inner and outer knob spindles 2D and 2|, respectively, upon which are mounted inner and outer knobs indicated. at. 22 and-- 23,. It will be understood that. the spindles 2H and. 2! are independently operable by their respective knobs so that either of the knobs may be rotated independently of the other to rotate the rollback carried thereby and retract the latch bolt. IZT. As the above-described structure and connections between the rollbaoks I-8 and I9 and belt 12 maybe identical with the corresponding parts shownin my previous patent referredto, it is deemed unnecessary to further illustrate them herein.

Slidably mounted intheopposite walls of the lock case- It is a plunger carrying a detent 26 adapted to engage in a recess 2-! ina laterally extended portion of the rollback l9 operatedby the outside knob, so that when theplunger is pushed inwardly from the position shown in Fig. 3-, and the detent engages in the-recess 21', the rollback I 3 will bedogged against operation.

Onefeature of the present invention relates particularly to thestructure: for operating the plunger 25. For this purpose-aplate-30ismounted upon the door, and, asillustrated, is at the inner face of the door. 'I his pIate-isof the form shown in Fig. 9, and is provided with openings 3 I. through which may bepassed: screws .by: which it. may be secured to the door-,- and also-with openings 32 for a purpose to be:hereinafter'described. Positioning lugs 33 areprovided near the peripheryv of the plate toassist inlocating thereon the. hollow. rose 34, which will be referred to hereinafter. The plate 30.15. also provided with a central. opening. 35lfor= passage of the knob spindles, the ends of which are-somewhatreduced in width with. respectetoithe centerthereof, as shownat 3E, and with slots3fl. above and below this opening. Also extending laterally from the opening. 35.are.recesses 38, the rear-wallsofzwhich are inclined, as shown in Fig. 3, so'thatattheir outer ends therecesses. aredeeper: than attheir inner portions adjacent theopening 35;

To. manipulate the plunger 25 a push button to, is secured theretoby means of the threaded connection 4|, and connectedatothis push: button is a lever or. walking beam; 425, shown moreparticularly. in Fig. 10,.having. an open-ended; recess 63 at one edge thereof toembrace a. reduced portion 44; of the.- pushbutton. an. The other end of the walking. beam, or; lever 42 is bent slightly,

as shown, at 45,.and,to.this;.end isusecured;a second push button 46, both of the buttons ln: and 46 projecting; outwardly through. openings. in. the rose 34.

Upon the walking beam; lever: 42 areiprQvlided semi.-circular-membersAflaandi lm onepair of-these members extending into the reduced ends= 3fi of the openingiii of; the plate30, so that this membergwill be rockably supported on this platez This memb r: is. held; against. the. plate; by a; bracket 1 gainst: whichthe other pair: ofrsemicircular memhersfilisandzw abut, the bracket being pro- I videdxwith. lugs 51: having reduced end portions 52 forced into the slots 31 of the plate 30. This bracket is provided with a central opening 53 for passage of the knob, and a wing 54 containing an opening 55 through which the push button 40 passesand in which it is guided.

As seen from Fig. 4, the outer rose 23 may be secured in place by means of screws 56 passed through the door and through the; inner rose 34, these screws passing through the openings 32 provided in the plate 30. With this construction the outer rose and knob which is rotatably secured thereto may be secured to the door from the inside, so that it may not be removed from the outside, the plate 30 not preventing this arrangement.

It. will beobvious with this construction that the Walking beam structure is mounted upon and carried bythe plate 30 and not by the rose, as is the. casein my prior Patent No. 2,268,973. It will also be apparent that in assembling the device, after the lock casing has been inserted through the edgeof the door, the-plate 30*with-the walking beams structureniounted thereonmay be secured to the face-0f the door, and the-push button 40 rotated. inthe slot 43* to connect it with the plunger 25. a

After the plate 30 has been secured in place therose may be applied to the plate; the push buttons. ML and 46 sliding through the openings irr the rose providedtherefor, and t-he rose being centered and positioneduponthe plate by the lugs. 33, which. contact the inner edge of the rim of the rose.

It. willv also be noted fronr Fig: 3 that this inner-rimof the rose-rests against the outer face of the plate 30 sothat asmall portion of this plate: is visible beyond the edge of the rose. The exterior surface of the rose is'stepped; as shown, and thisexposed-portion of the plate'merely provides what-appears toabe anadditional step so that. it. does not detract fromthe appearance of the:1DCkL. Moreover; it Willbe observed that, as shown in Fig. 3, the provision of therecesses. 38 Willqpermitthe rear ends of the walking beam to. pass. beyond the outer surface oi theplate 30 and lie: in. these recessed so' that the walking beam is .provided with a greater throwthan would normally be providedby the-depth of the rose ii: the; outer: surfaceof the plate were unbroken. The plate 30 isrelatively thick;- and the recesses 38: thus provide a considerable additional" throw for' the-lever 42; thus making itpossible to use a rose 3410f: standard form for a-lockprovidedwith a'. walking beam mounted or housedwithin the rose,- whichhas not been possibleheretofore;

InFigs. 6.to 8;o"the= drawings I have shown the. presentzdogging' structure applied to a standard mortise. lock; As: shown, this look is provided; with; a, case; so in which is. reciprocably mounted. the latch; b.olt;62le haying a stem. 62 and crosshead, 63., the latter; being: engaged by-- the end 64 of a retractingayoke: fi5rwhichiyoke is-actuated by inner: and. outer: rollbacks; it]; and 68. These rollbacks are operated; lay-inner; and outer spindles. 6.8 and. 69,,respeotively, up,on which. are mounted. knobs. 10. and H, it. being understond that the, spindles are independent-131- rotatable.

As, shown, the rollback 6.6: extendsbeyondg the rollbackfil and .isprovidedlwith; arecess 72 within which may engage a dogging detentrl3-onrazdog ging plunger 14, similar tothe plunger 25, shown in Fig. 3. The mechanism. for, operating. the plunger 14 is the same, asthatshown. in Fig.3 andcomprises the same walking beam structure mounted" on and carried by the plate 30 and housed Within the rose 34. A detailed description of this structure is, therefore, unnecessary.

It will also be understood that the dogging plunger 14 is slidably mounted in the opposite walls of the casing 60, as shown in Fig. 8, so that it is properly guided in its in-and-out sliding movements.

In this manner my improved dogging mechanism may be readily applied to a standard mortise lock, in which event the mechanism for dogging the outer knob will be mounted at the inside of the door adjacent the inner knob spindle instead of being mounted, as has been the custom, at the edge of the door in the face plate 60* of the lock case. Thus it will be unnecessary to open the door to set the dogging mechanism, even when a mortise lock is employed.

While I have shown and described some preferred embodiments of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the claims.

What I claim is:

1. In a door look, a case, a latch bolt reciprocably mounted in the case, inner and outer knobs operatively connected to the latch bolt to retract the same, a dogging member to dog the outer knob against rotation, said member being slidably mounted in the case for movement transversely to the bolt, a supporting plate secured to the inner face of the door, a hollow rose member having its base resting upon said plate to be spaced therebyirom the face of the door, a walking beam, means rockably securing said walking beam to said plate between the latter and the face of said rose member, said walking beam being connected to the dogging member to operate the same, operating means for said walking beam extending through the face of the rose,

and said plate being recessed at its outer face.

to receive the ends of the walking beam to permit a long throw of the latter relatively to the depth of the hollow rose member.

2. In a door look, a case, a bolt reciprocably mounted therein, independently rotatable inner and outer knobs, mechanism connecting each of said knobs to said bolt for operation thereof, a dogging member slidably carried by the walls of the case to dog the outer knob against operation, a walking beam structure for operating the dogging means accessible for operation at the inside of the door when the latter is closed, a supporting plate secured to the inner face of the door, a hollow rose member having its peripheral edge resting against said plate, means rockably mounting said walking beam structure on said plate within said rose, said structure including a lever, and said plate being recessed on its outer face to receive the ends of the lever whereby the latter is permitted a relatively long throw, and operating means connected to the lever and projecting through the rose.
